Biofuels derived from lignocellulosic biomass have great potential to solve the problems related to petroleum fuel usage, with advantages of lower CO2 emission and sustainability. Pyrolysis is one of the most promising thermal conversion of lignocellulosic biomass. However, pyrolysis oil from pyrolysis process of lignocellulosic biomass, which is complex mixtures of oxygenated molecules, is responsible for high acidity and low energy density. Therefore, many research groups have focused on the upgrading of pyrolysis oil, preferably via hydrodeoxygenation (HDO), to utilize the hydrocarbon fuels and chemical production. The aim of the present work is to investigate the performances of the nickel-based catalyst supported by SBA-15 to convert bio-tar into less oxygenated compounds in supercritical ethanol environment. Among the catalysts, Mg-Ni-Mo/SBA-15 was highly active to enhance deoxygenation of bio-tar, leading to the formation hydrocarbons and aromatics. |
